Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the motor is mounted within the outer casing by welding, then the motor is securely fixed, but the installation becomes complicated and the installation cost increases significantly
Solution Approach 1:
The housing is divided into a first housing body and a second housing body that can be assembled together, allowing the motor to be mounted on the first housing body and then the second housing body to be attached, simplifying the installation process while maintaining secure fixation
Solution Approach 2:
A motor mounting plate is introduced as an intermediary component between the motor and the housing, providing a standardized mounting interface that simplifies installation while ensuring secure and stable motor fixation
2Ease of manufacture
If the outer casing is configured as a single integrated structure, then the manufacturing cost is high for precise motor fitting, but the air flow configuration cannot be easily modified to minimize noise
Solution Approach 1:
The housing is segmented into a first housing body and a second housing body, allowing independent optimization of each part - the first housing body can be designed for cost-effective manufacturing while the second housing body can be configured for optimized air flow and noise reduction
Solution Approach 2:
Different parts of the housing have different functions and configurations - the first housing body focuses on motor mounting and structural support, while the second housing body focuses on air flow configuration and noise minimization, allowing each part to be optimized for its specific purpose
3Ease of manufacture
If the motor is mounted by screw structure, then the installation is simpler, but the motor cannot be securely mounted and unwanted vibration is generated
Solution Approach 1:
The motor mounting plate combines multiple functions - it provides screw mounting interfaces for simple installation, structural reinforcement for secure fixation, and vibration damping features, merging simplicity and reliability into a single component
Solution Approach 2:
The motor mounting plate is made of a composite structure or material that combines rigid elements for secure mounting with vibration-damping elements, providing both easy installation and stable operation
4Reliability
If the outer casing is made large enough to hold the motor between top and bottom walls, then the motor is stabilized, but the overall weight of the air mover increases significantly
Solution Approach 1:
The housing is divided into two housing bodies that can be assembled together, allowing the motor to be mounted on the lighter first housing body, reducing the overall weight while maintaining stabilization through the combined structure
5Device complexity
If no air filter is provided at the air inlet, then the structure is simple, but dust accumulates at the motor reducing efficiency and pollutes the drying surface
Solution Approach 1:
The housing is segmented to include a detachable air filter component that can be easily installed and removed, maintaining relative structural simplicity while providing dust filtration to protect motor efficiency

AI summary
An air mover includes a housing and an air stream generator. The housing includes an air exit, a first housing body and a second housing body symmetrical to the first housing body in size, wherein the first housing body has an perforated end panel formed at an outer side thereof. The air stream generator includes a motor coupled at an interior side of the end panel of the first housing body via a locking mechanism and a impeller being powered by the motor to generate an air stream exiting at the air exit. The locking mechanism is securely locked up the motor at the end panel of the first housing body from an exterior side of the end panel such that the motor is securely supported at the end panel of the first housing within the housing cavity.
